Is This a Sweet Potato Plant?

I planted sweet potatoes and have several of these big beautiful plants now growing with yellow, red and lilac colored flowers. In other places where I planted the same sweet potatoes are the typical looking vine plants with flowers that look like morning glories.

Noope. It's a nicotiana, or flowering tobacco (not smokeable). They plant themselves from year to year. I guess your sweet potatoes didn't make it. But aren't they pretty?

My Four O'Clocks look just like this plant. So that is what I think it is possibly a yellow four O'Clock

Hello! Whether it is Mirabilis jalapa or ornamental tobacco is very easy to find out : wonderful scent from the flowers of the four o'clock flower (Mirabilis jalapa) that produce a black seed as big as a green pea and which tubercle look like a black radish. The Ornamental tobacco leaves are lighter green, sticky and hairy. Hope this helps!
